Please excuse me as I am new to this forum!  I would like some advice on the best puppy food for a Bullmastiff, she has come with Eukanuba but have also been told Pro Plan is very good as well, wondering if anyone has had experience of these and which they have found best?

We always fed our Bullmastiff on Royal Canin Puppy large breed then junior,and finally Adult..We feed our Mals on Barf.
